TAP CONNECTION FOR KEGS.

ll'o all whom "it may concern:

Be it known that I, HENRY O. l/Vlnnnimn, citizen of the United States,residing Detroit, county of l Vayne, State of Michlgan, have invented acertain new and useful 11nprovement in Tap Connections for Kegs, anddeclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to tap-connections for kegs, half barrels, wholebarrels and other size packages and has for its object a tap-connectioncomprising a tap-bushlng with screw threads on the outside thereof and atap-ring or nut adapted to run on said threads and securely draw thehead of the keg to the inner receptacle to which the tap-bushing isfastened by welding or brazing. This form of construction removes thethreads from a place where they will be subject to moisture and where,also, the rusting might taint the contents of the inner receptacle. Thisalso allows the inner surface of the bushing to be enameled, and doesaway with the danger of leakage which might be caused by threadedjoints.

In the drawings :-Figure 1, is a section of a portion of the kegincluding its head, showing the tap-connection in position. Fig. 2, is asection of the tap-connection. Fig. 8, is a top elevation of thetap-connection, the cap being removed. Fig. 1, is an elevation of theinside of the cap. Fig. 5, is a section of the cap.

A, represents the side portion of a keg and B the head of the keg. Thetap-hole 1 is bored in the head of the keg with an irregular bore tocorrespond with the shape of the tap ring ornut, so that the bore,through the head, is of smallest diameter on the inside of the keg andflares out a little below the center of the head. as shown in thedrawings. The tap-bushing 2 is welded to the inner metallic receptacle 3which is provided with a coat of enamel 4; reaching part Way up into theinside of the tap bushing. The outside of the tap-bushing is threaded atthe inner end as at 5 and on these threads runs the cup shaped tap-ringor nut 6 that is flanged at its outside end 7 This flange 7 is adaptedto engage the outside of the head and when the tap-nut or ring is turnedupon the bushing, it draws the head securely Specification of LettersPatent.

against the inner receptacle so as to fasten them firmly together. Theoutside end of the tap-bushing 2 is provided with a flange 8 whichserves as a seat for the cap 9. The flange 8 is notched at either sideat 10, so that the inward projecting lugs 11 of the cap may slide downunder the flange and engage with the under side of the flange, which isinclined, as shown at 12 (dotted lines in Fig. 2). The lugs 11 arecorrespondingly beveled so that when the cap is given a portion of aturn, the lugs 11 011 either side of the cap engage with the underinclined surfaces 12 of the flange portions on either side of the tapbushing so as to screw the cap seciirely to the tap-bushing and seal thecas z.

The above construction allows the enameling of the tap bushing on theinterior to any desired height so that this, as well as the innerreceptacle, may be kept clean and free from rust. The threads arelocated on the outside of the tap-bushing so that they neither interferewith the contents of the inner receptacle nor are they subject tocorrosion from the contents of the inner receptacle, while the nutserves to securely draw the head to the inner receptacle by takingadvantage of the mechanical power of the screw.

What I claim is 2- 1. The combination of a barrel provided with a headhaving an aperture and a metallic receptacle contained in the barrel, ofa tap connection comprising a bushing attached to the inner metallicreceptacle and projecting through the aperture in the head, the saidbushing being externally threaded near its inner end and a cup-shapednut spaced from the outer portion of the bushing to form acircumferential groove therewith and turned in toward the bushing at theinner end and screw-threaded at such inner end to engage thescrew-threads of the bushing, the said nut having an annular flangeadapted to engage the substance of the head to draw the same to theinner receptacle, substantially as described.

2. The combination with a barrel provided with a head having an apertureand a metallic inner receptacle contained in the barrel, of a tapconnection comprising a bushing welded to the inner receptacle andexternally screw-threaded near such welded connection, and a cup-shapednut threaded at its inner end to engage the threads of the bushing andflaring out from the bushing In testimony whereof, I sign this specifitoform a olrculnferentlal groove, the said cation 1n the presence of twoWitnesses.
